JFileChooser always to the front

Here is a demo. Run the demo with vm 1.4 (some users may still have this version) and click onto "Open dialog", then "Open file chooser". Then you click somewhere onto the dialog, the filechooser moves behind the dialog. When you run the demo with java version 5, the dialog behaves like the frame:

import java.awt.event.*;

import javax.swing.*;
